Could Emsculpt treatment on buttocks cause sciatica?

I received a full series of emsculpt treatments to my buttocks 3 months ago. A couple of days after the last session, I had sciatic pain for the first time in my life. I have continued to have it since. Could the sciatic pain I’m experiencing be because of the emsculpt? Or just a coincidence? I’d like to have the recommended top up but don’t want to exacerbate the problem.
